UNITED STATES. PATENT orrion EMILE GABRIEL ROYER, OF PARIS, FRANCE,.ASSIGNOR TO SOCIE'IF ANONYIVIE ORIONA. OF BRUSSELS, BELGIUM.

To all whom it may concern:

Be it known that I, EMILE GABRIEL Roman, a citizen of the FrenchRepublic, and resi dent of Paris, France, have invented certain new anduseful Improvements fin Electric Incandescent Lamps, of which thefollowing is a specification.

This invention relates to improvements in electric incandescent lamps,the object of the improvement being to so arrange the filaments as toprevent the casting of shadows,

..Fig.

and to increase the range of the light thrown ofi by the lamp.

The invention also co-mprehends improvemerits in the details ofconstruction and arrangement of parts which will be hereinin the claims.

In the drawings: Figure 1 is an elevation of one form of my improvedlamp. Fig. 2 is a bottom plan view of the same. Fig. 3 is an elevationof another form of the invention. Fig. 4 is'a bottom plan view of thesame. I I} -1 indicates abulb, providedmiith a'socket 2. Dependingfrontthesocket is a rod 27, aving two spaced apartcollars from whichextend outwardly projecting hooks 28. At

the bottom of the rod is a head 30, from which extend downwardlyinclined hooks 31, A filament is supported on the books 28, insubstantially a series of vertical strands arran ed in cylindrical formas shown in l the ends of the filament being connected to the lead'-wires-33 and'34. This filament will throw from the lamp, as will beobvious.

A filament 32, is supported on the hooks 31, and is arranged in ahorizontal plane below the filament 29. The strands .of the filament 32,extend beyond the vertical plane of the filament 29, to ofi'set theshadows which may be thrown by the latter. Filament 32, is designed tothrow the rays of light downwardly from the lamp. The ,termmals of thefilament 32, are connected to the lead wires 33 and 34, as shown in Fig.1.

In the form of the invention shown in Specification of Letters Patent.

particularly pointed out the rays 0% light radially lower annularPatented July 1, 1913. Serial No. 606,605.

Figs. 3 and 4, the central stem 43, in the. bulb 1 is provided with twocollars 44 and 45. Extending radially from the collar 44, are hooks 46,while irom the collar'45, ex' tend vertical hooks 47. The distance fromthe center of the stem-43, to the ends of the hooks 46, is much greaterthan the distance from the center of the stem to the hooks '47,consequently the strands of the filament, indicated at 48, supported bythe hooks, incline upwardly so that the rays of light are thrownradially and downwardly;

Depending'from the collar 45, are hooks 49, and horizontally supportedon these hooks are'the strands of a filament 50, I

which throw the rays of light downwardly.

From the foregoing description it will be seen that I have provided anincandescent lamp which will throw out the rays'of light radially'anddownwardly in suchmanner as to avoid shadows. i

I claim Y 1. In combination, a globe, a standard mounted centrally inthe globe, annular supports mounted on the standard, and a l ilalnentsecured on the supports, a part of said filaments extending verticallybetween the supports and another part of said fila Inent extendingtransversely across the central plane of the standard;

2. In combination, a globe, at standard centrally mounted in the globe,,upper and lower annular supports mounted on the standard, hooksextending from the annular supports, a support at the bottom of thestandard, and a filament extending'from the hooks on the annularsupports in substantially (vertical l'ines, said filament also extendingacross the support at the bottom of thestandard and across the verticalplane of the upper 'and lower supports.

3. In combination, a globe, a standard, centrally mountedin the globe,upper and supports mounted on the standard, hooks on the annularsupports, an annular support at the bott'onrof the standard, said lattersupport being of greater di- 95 ameter than the upper and lower annularsupports, and a filament supported on the In testimony whereof I"ha'.i'e herennto set hooks betkeen the upper and lower Sn'pports my hand inpresence of two witnesses. and also extending across the support on thelower end of the standard, the part of EMILE GABRIEL the filamentextending across the lower an- Witnesses:
